Supports RAW camera files (ARW, CR2, CR3, DNG, NEF, etc.), HEIC/HEIF, and standard formats (JPEG, PNG, WebP, BMP, TIFF, GIF). Optionally applies Lightroom XMP sidecar edits to RAW files.

Note: This is proof-of-concept code. It may be unreliable and is not actively maintained.

Install#

cargo install avify

HEIC/HEIF support is enabled by default but requires libheif system libraries. To install without HEIC:

cargo install avify --no-default-features

macOS (with HEIC)#

Install libheif dependencies, then build:

brew install pkgconf libde265

See build.sh for a script that builds a minimal decode-only libheif from source.

Usage#

avify [OPTIONS] [FILES]...

If no files are given, converts all supported images in the current directory.

Options#

Flag	Description	Default
`-q, --quality`	Encoding quality (0-100)	80
`-s, --speed`	Encoding speed (1-10, higher = faster)	10
`-o, --outdir`	Output directory for AVIF files	same as input
`-m, --move-originals`	Move originals to this directory after conversion
`-t, --trash`	Trash originals after conversion (macOS)
`-x, --xmp`	Apply Lightroom XMP sidecar edits

Examples#

avify *.jpg

avify -q 90 -s 6 photo.arw

avify -o converted/ -m originals/

avify -x raw_photos/*.cr3

Features#

Parallel encoding via rayon — uses all CPU cores
RAW support via imagepipe (ARW, CR2, CR3, DNG, NEF, ORF, RAF, RW2, PEF, SRW, X3F)
HEIC/HEIF support via libheif (optional, enabled by default)
XMP sidecar edits — applies Lightroom exposure, contrast, highlights, shadows, white balance, crop, saturation, and vibrance adjustments
10-bit AVIF output for better color depth
